Default Homone Rooting Powder NAA


"gray bale" wrote in message
...
I am told that the hormone rooting powder you normally buy is Beta
Naphthaleneacetic Acid (NAA).

But the commerical growers use Alpha Naphthaleneacetic Acid (NAA).

Anybody have any experience of this, or even where I can get some from ??

You'll probably only be able to get it in commercial packs and it's
expensive.
I got all I've forgotten about plant propagation from
Hartmann & Kester - 'Plant Propagation Principles & Practice' Prentice Hall
Nov 2001 ISBN: 0136792359

The early edition I have is at work so I can't look it up for you atm. Try
and order it from your local library or the RHS Lindley library. Still the
propagator's bible.
